The BBC's latest nature show is hot on the heels of David Attenborough's Frozen Planet and has some high expectations to meet, but David Tennant does a fine job curating this birds-eye view of the world.

This week the show (BBC One, 8pm) takes us over Africa's landscape and wildlife, showing Cape gannets joining sharks, dolphins and whales as they feed off shoals of sardines. Also featured are kelp gulls following the trail of great white sharks, eagles diving for fish in the Zambezi river and vultures witnessing the wildebeest migration on the Serengeti.

The next three weeks are no doubt going to include chatter about the antics in the Celebrity Big Brother house. If you want to have a clue who people are talking about, or nature's not your bag, the launch show of Channel 5's CBB begins at 9pm with promises of screaming, fake tan and some hilarious introductions between celebrity egos.
